Name Type Required Description
ignore_null_empty bool Indicates whether to ignore null/empty columns and exclude them from the resulting property bag. The default value is false.

Example

The following query will use pack_all() to create columns for the below table.

SourceNumber TargetNumber CharsCount
555-555-1234 555-555-1212 46
555-555-1234 555-555-1213 50
555-555-1313 42
555-555-3456 74
datatable(SourceNumber:string,TargetNumber:string,CharsCount:long)
[
'555-555-1234','555-555-1212',46,
'555-555-1234','555-555-1213',50,
'555-555-1313','',42, 
'','555-555-3456',74 
]
| extend Packed=pack_all(), PackedIgnoreNullEmpty=pack_all(true)

Output

555-555-3456 74 {"SourceNumber":"", "TargetNumber":"555-555-3456", "CharsCount": 74} {"TargetNumber":"555-555-3456", "CharsCount": 74}

Note

There is a difference between the Packed and the PackedIgnoreNullEmpty columns in the last two rows of the above example. These two rows included empty values that were ignored by pack_all(true).
